Adjustable multifunctional fractured rock mass collapse-slide testing device and use method of adjustable multifunctional fractured rock mass collapse-slide testing device

Abstract

The invention discloses an adjustable multifunctional fractured rock mass collapse-slide testing device and a use method of the adjustable multifunctional fractured rock mass collapse-slide testing device. The adjustable multifunctional fractured rock mass collapse-slide testing device comprises a gathering zone support, a collapse-slide rail support, a stretchable rod A, a stretchable rod B, a gathering zone testing tank and a collapse-slide rail testing tank. The two ends of the bottom of the gathering zone testing tank are connected with the upper portion of the stretchable rod A. The two ends of the bottom of the collapse-slide rail testing tank are connected with the upper portion of the stretchable rod B. The gathering zone support and the collapse-slide rail support are installed on a base supporting plate and a distance adjustment sliding rail base through thread fasteners. A partition plate in the collapse-slide rail testing tank is pulled out, fractured rock mass materials collapse and slide down, pass through a slope material containing tank to reach the gathering zone testing tank and gradually stop moving in a gathering zone, a time of fractured rock mass gathering process test is completed, and the testing result is recorded. By means of the adjustable multifunctional fractured rock mass collapse-slide testing device and the use method, the fractured rock mass collapse-slide process researching test has the repeatability, the complementariness and the verification performance, and the adjustable multifunctional fractured rock mass collapse-slide testing device and the use method have the advantages of being capable of being disassembled and assembled, and being easy and convenient to operate, diverse in function and high in repeatability.

Description

technical field [0001] The invention relates to the fields of geotechnical technology in civil engineering and earthquake resistance and disaster reduction engineering, in particular to an adjustable and multifunctional broken rock mass avalanche test device and a use method thereof. Background technique [0002] As a special solid medium, rock mass often contains weak planes such as layers, joints, and fissures. The existence of these discontinuous structural planes weakens the mechanical properties of rock mass and is also the main factor leading to rock mass failure. The so-called broken rock mass refers to the rock mass with smaller block diameter and more cracks produced under the action of natural weathering, geological movement or human activities. At present, there are a large number of broken rock masses in some strongly weathered geological structures along roads in mountainous areas and around towns in remote areas, which has caused certain problems for the dispos...

AI Technical Summary

Problems solved by technology

[0006] 1. It is inconvenient to assemble and cannot be disassembled:

[0007] Existing test devices are often designed for a specific situation, so the connection is often designed to be fixed, that is, designed to be non-detachable, resulting in a waste of resources

[0008] 2. The function of the device lacks diversity:

[0009] Because when doing simulation tests, it is often necessary to verify the influence of several or even multiple parameters on the test results. Therefore, it is necessary to design multiple groups of tests and compare them with each other to obtain valuable conclusions. The existing test device has a single function and cannot satisfy the testers. Need to study multiple factors, lack of functional diversity
